Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a floor cleaning tool capable of cleaning the ground. Background Technology

[0002] In both everyday and commercial cleaning, mops are one of the most common wet floor cleaning tools. Their cleaning effectiveness largely depends on the proper wetting of the cleaning cloth (or mop). Currently, mainstream wet cleaning solutions are mainly divided into two types, but both have significant technical shortcomings and user experience deficiencies.

[0003] The first method is pre-wetting. This involves soaking a dry cleaning cloth in water or diluted cleaning solution before use, wringing it out to a certain degree, and then attaching it to the mop head. Alternatively, disposable cleaning cloths (wipes) pre-soaked in cleaning solution can be used directly. This method has several drawbacks: First, the manual soaking and wringing process is tedious and laborious, and the degree of wetness depends entirely on the user's experience, making it difficult to maintain a consistent and optimal state. Second, while disposable pre-wetted cleaning cloths are convenient, they are expensive, resulting in high long-term costs. More importantly, these products contain liquid, and to prevent evaporation and degradation, they must be stored and transported in individual sealed packaging. This not only increases packaging material consumption, contradicts environmental protection principles, but also creates inconvenience for users in terms of procurement, storage, and management.

[0004] The second type is the real-time liquid application solution. To overcome the shortcomings of the pre-wetting solution, mops equipped with a liquid storage tank and application mechanism have appeared on the market. Users can fill the storage tank with clean water or cleaning solution, and during the mopping process, they can manually press or electrically control the liquid to deliver it to the cleaning cloth. However, the core drawback of this solution is that it is difficult to control the amount of liquid applied. If too little liquid is applied, the cleaning cloth is in a semi-dry state, resulting in poor cleaning effect and easy dust generation during dry wiping; if too much liquid is applied, the cleaning cloth becomes instantly oversaturated, unable to effectively absorb and lock in the liquid, causing the excess liquid to be squeezed out and remain on the floor surface, forming water stains or liquid stains that are difficult to air dry. These liquid stains not only affect the appearance after cleaning, but also dissolve dirt in the floor gaps, forming a dirty film and causing secondary pollution to the floor. For wooden floors, excessive liquid penetration may even cause deformation, mold, and shorten their service life. Utility Model Content

Detailed Implementation

[0018] This application relates to a floor cleaning tool that can wipe the floor using a cleaning cloth moistened with liquid; the cleaning cloth can be a disposable sheet-like cleaning mop or a reusable cleaning mop. Furthermore, the floor cleaning tool can also be equipped with a vacuuming function, meaning it simultaneously performs both vacuuming and wiping functions.

[0019] See Figure 1 , Figure 2 , Figure 3 and Figure 4This illustration shows an embodiment of a floor cleaning tool according to this application. The floor cleaning tool 100 is constructed as a push-stick cleaning tool, which includes a cleaning head portion 1, an upright portion 2, and a portable vacuum cleaner main unit 3. The cleaning head portion 1 is rotatably connected to the upright portion 2, and the upright portion 2 is detachably connected to the portable vacuum cleaner main unit 3.

[0020] Reference Figure 2 The upright part 2 includes a housing 21, a liquid supply container 22, and a handle 23. The liquid supply container 22 is detachably mounted on the upright part 2. The liquid supply container 22 can be a reusable component or a replaceable component. The liquid in the liquid supply container 22 can be clean water or a cleaning solution. The handle 23 is mounted on the upper part of the housing 21. The lower end of the housing 21 is rotatably connected to the cleaning head part 1.

[0021] The housing 21 also houses a fluid pump 24 for supplying liquid from the supply container 22 to the outside. In this embodiment, the housing 21 also includes a three-way connector 25 located downstream of the fluid pump 24. One end of the three-way connector 25 is in fluid communication with the outlet of the fluid pump 24, and the other two ends are connected to a pair of outlet pipes 26; that is, the liquid output from the supply container 22 is split into two streams by the three-way connector 25 and supplied externally. The housing 21 also has a button 27 for starting the fluid pump 24.

[0022] See Figure 3 , Figure 4 The cleaning head part 1 includes a housing 11, a pair of transparent viewing windows 12, a pair of nozzles 13, a pair of shoulders 14, a rotary joint 15, and a suction nozzle component 16.

[0023] A cleaning cloth (not shown) is detachably attached to the housing 11. The cleaning cloth, when attached to the housing 11, can contact the surface to be cleaned. Four cloth corner locators 111 for securing the cleaning cloth are provided on the top of the housing 11. Each cloth corner locator 111 is a flexible component with a slit, configured to removably engage one corner of the cleaning cloth.

[0024] The top of the housing 11 also includes a pair of transparent viewing windows 12, which are configured to allow the user to observe the condition of the cleaning cloth. The pair of transparent viewing windows 12 are symmetrically embedded on the top of the housing 11, one on the left and one on the right, and are recessed downward relative to the top surface 110 of the top of the housing 11.

[0025] The transparent viewing window 12 is also provided with several drainage holes 121 leading to the cleaning cloth; that is, liquid can flow to the cleaning cloth through these drainage holes 121, thereby wetting the cleaning cloth. And the user can observe the wetting status of the cleaning cloth at any time through the transparent viewing window 12.

[0026] In this embodiment, the transparent observation window 12 is designed as an "isosceles trapezoid", which expands the coverage of the leakage hole 121 on the cleaning cloth from a narrow width to a wide width, actively guiding the liquid to spread from the center to both sides, ensuring that the entire width of the cleaning cloth can be quickly and evenly wetted, thereby improving cleaning efficiency and effect, and avoiding leaving uneven water marks on the ground.

[0027] A pair of protruding shoulders 14, arranged horizontally, are provided at the top center of the housing 11. A rotary joint 15 is supported between the pair of protruding shoulders 14. A pair of nozzles 13 are respectively supported on the pair of protruding shoulders 14 and located outside the pair of protruding shoulders 14. The pair of nozzles 13 are also located above a pair of transparent viewing windows 12. The pair of nozzles 13 are in fluid communication with a pair of water outlet pipes 26.

[0028] The nozzle assembly 16 includes a nozzle 161 and a pair of rotating arms 162, which are rotatably connected to a pair of shoulders 14 on the top of the housing 11. Thus, the nozzle assembly 16 is rotatably connected to the housing 11 via the rotating arms 162. When the user needs to attach a cleaning cloth to the housing 11 or when vacuuming is not required, the nozzle assembly 16 can be rotated upwards to the upper side of the housing 11. A flexible conduit is connected to the rear end of the nozzle 161 and passes through a rotary joint 15.

[0029] In this embodiment, the upright portion 2 has a fluid channel (not shown) extending from the upper end of the handle 23 to the lower end of the housing 21, and the fluid channel is in fluid communication with the nozzle 161. When attached to the upper end of the handle 23, the portable vacuum cleaner main unit 3 is in fluid communication with the fluid channel, thereby allowing dust-laden airflow to be drawn from the nozzle 161 into the portable vacuum cleaner main unit 3. In other embodiments, the portable vacuum cleaner main unit 3 may also be mounted at other locations on the upright portion 2, such as on the housing 21.

[0030] In this embodiment, when the cleaning tool 100 is working, the process of wetting the cleaning cloth is as follows: Pressing the start button 27 activates the liquid pump 24, which supplies liquid from the supply container 22 to a pair of nozzles 13. The liquid sprayed from the pair of nozzles 13 flows onto the cleaning cloth through the leakage holes 121 on a pair of transparent viewing windows 12. During the wetting process, the user can observe the wetting status of the cleaning cloth at any time through the pair of transparent viewing windows 12, thereby controlling the liquid spraying as needed. When vacuuming is required simultaneously, the portable vacuum cleaner main unit 3 is started, and dust can be sucked up through the nozzle 161. If it is necessary to wipe the cleaning cloth along the edge, the nozzle component 16 can be moved backward and upward, exposing the front edge of the housing 11 and the cleaning cloth, thereby achieving edge wiping.

[0031] The above embodiments are merely illustrative examples, and those skilled in the art can make equivalent substitutions or improvements within the scope of the claims. Other embodiments, besides the exemplary embodiments shown and described herein, are also covered within the scope of this invention.
